2 Claims. (Cl. 189-76) aluminum have been found to be particularly suitable in manufacturing such window structures. However, they have not been entirely successful due to difficulties in joining certain of the components employed therein such as the rails and stiles of the sashes.

It is an object of the invention, accordingly, to provide metallic window sashes that are particularly susceptible of being manufactured from lighter metals such as aluminum.

It is a further object of the invention to provide window sashes of the above character including connecting tabs capable of being formed'by a simple striking operation.

It is still another object of the invention to provide window sashes of the above character formed from extruded members adapted to be easily assembled and welded together with the aid of connecting tabs struck out of such members.

These and other objects of the invention are accomplished by providing rail and stile members preferably extruded from a lighter metal such as aluminum. A striking out operation on the webs of the stiles provides suitable tabs that cooperate with the appropriate rail members and may be welded thereto, the resultant sash being a rigid inexpensive structure.

Further objects and advantages of the invention will be understood when the following description is read in connection with the accompanying drawings in which:

Fig. 1 is a view in elevation of a metallic window structure formed in accordance with the present invention, this structure illustrating a conventional double hung window;

Fig. 2 shows a portion of the upper sash of the window structure of Fig. 1 in elevation, partially cut away and considerably enlarged;

Fig. 3 is a view in longitudinal section of the upper sash taken on the line 33 of Fig. 2 looking in the direction of the arrows;

Fig. 4 is a transverse section of the upper sash taken on the line 44 of Fig. 2 looking in the direction of the arrows;

Fig. 5 is another transverse section of the upper sash on the line 55 in the direction of the arrows;

Fig. 6 shows a portion of the lower sash of the window structure of Fig. l in elevation, partially cut away and considerably enlarged;

Fig. 7 is a view in longitudinal section of the lower sash taken on the line 77 of Fig. 6 looking in the direction of the arrows;

Fig. 8 is a transverse section of the lower sash taken on the line 88 of Fig. 6 looking in the direction of the arrows; and

2,115,325 Patented Dec. 25, 1956 Fig. 9 is another transverse section of the lower sash taken on the line 99 of Fig. 6 in the direction of the arrows.

Referring to the drawings and particularly to Fig. 1, an upper sash 10 and a lower sash 11 are slidably mounted in a conventional window frame formed by a head 12, a sill 13, and jambs 14 joining'the ends thereof. These members may be mounted in masonry in any convenient manner, such mounting being well-known in this art.

Referring next to Figs. 2 to 5, inclusive, an upper rail 15 is preferably extruded from light metal stock, such as aluminum, to a box-like configuration having a slot 15a formed therein. Therefore, the interior of the upper rail 15 is defined by a pair of vertical walls 15b and 15c terminating at two horizontal walls 15d and 152. A retaining member 16a is secured in the slot 15a in a conventional manner, such as by a press fit, and cooperates with the rail 15 to form achannel 16 for receiving a window pane 17.

A stile 18 is formed by a web 19 carrying outwardly extending flanges 20 and 21, adapted to slidably engage suitable recesses in the jamb 14, and a channel 22 to secure the window pane 17, all formed integrally as, for example, by means of extruding metal such as aluminum in a conventional manner. Tabs 23, 24, 27 and 28 are preferably struck out of the web 19 near each extremity thereof so that they project substantially perpendicular thereto.

A meeting rail 25, also preferably extruded from light metal stock to a box-like shape, has a channel 26 formed therein to receive the window pane 17. The rail 25' also carries a tongue 29 integral therewith and adapted to cooperate with the lower sash 11. The interior of the meeting rail 25 is defined by vertical walls 25a and 25b respectively terminating at their lower ends with a horizontal wall 25c and at their upper ends with horizontal walls 25d and 252, respectively, joined by a wall 25f.

In assembling the sash, the upper rail 15 and the meeting rail 25 are positioned and squared with respect to the stiles 18 with the aid of the tabs 23, 24, 27 and 28. It will be observed that the horizontal edges of the tabs 23, 24, 27 and 28 engage the respective horizontal walls 15d, 15e, 25c, 25d and 25e found in the upper and meeting rails 15 and 25. The sash may then be permanently formed by spot welding the tabs to the rail walls or by conventionally welding the tabs to the walls through the openings formed in the web 19 by the striking of the tabs therefrom.

Referring next to Figs. 6 to 9, inclusive, the lower sash 11 is shown as generally formed from a meeting rail 40 and a bottom rail 41 connected by a stile 42. The

meeting rail 40, preferably extruded from light metal stock to an appropriate box-like configuration, includes a channel 43 integral therewith serving to carry a window pane 44. A second channel 45 running along one side of the rail 40 carries weather stripping 46 adapted to cooperate with the tongue 29 on the upper sash 10. The interior of the meeting rail 40 is defined by vertical walls 40a and 40b terminating at their upper ends at a horizontal wall 400 and at their lower ends at horizontal walls 40d and 402, respectively, joined by a wall 40f.

The bottom rail 41 is also extruded to a box-like configuration and has a slot 41a formed therein. A retaining member 46a is secured in the slot 41a in a conventional manner and cooperates with the rail 41 to form a channel 46, designed to secure the window pane 44. A handle 47 is found on the rail 41 and is adapted to be engaged for lifting the sash 11. Also provided on the rail 41 is weather stripping 48 and 49 adapted to sealably engage the sill 13 of the window frame. The interior of the bottom rail 41 is defined by a pair of vertical walls 41b and 41c, their upper ends terminating at a horizontal wall 41d and their lower ends at horizontal walls 41e and 41 respectively, joined by a wall, 41g.

The stile 42 is similar to the stile 18 and consists of a web 50 carrying flanges 51 and 52 and a channel 53 thereon to receive the window pane 44. The flanges 51 and 52 are adapted to be slidably engaged by the jambs 14.

Struck out of the extremities of the web of the stile 42 are tabs 54, 55, 56 and 57 cooperating with the rails 40 and 41, respectively, when fitted therein. It will be observed that the horizontal edges of the tabs 54, 55, 56 and 57 engage the respective horizontal walls 40c, 40d, 40e, 41d, 41e and 41f found in the meeting and bottom rails-40 and 41. These tabs are employed to aid in the assembly of the sash 11 and are preferably joined to the rail walls by welding, as indicated in discussing the upper sash 10, to complete the structure.

Accordingly, it is evident that the invention provides sashes of great rigidity that may be formed by a relatively small number of simple manufacturing operations, such operations being facilitated by the keying and squaring action of the tabs in the assembly stage and the Welding of the tabs to the rails in the final stage. I

It will be understood that the above embodiment of the invention is illustrative only and modifications will occur to those skilled in the art. For example, certain plastics may lend themselves to this type of construction in place of light metals. Therefore, the invention is not to be limited to the specific apparatus disclosed herein but is to be defined by the appended claims.
